, как вы видите, каждый шаблон имеет в templateArray, каждый объект содержит элемент categoryArray, подобный этому categoryArray: "sports, holidays"

Iтакже есть filteredTemplateArray:[]

selectedCategoriesArray:[],
    categories: ["Holiday","Sports","Misc","Automotive","Retail","Financial","Church","Community","Food"],

Вот код конца шрифта для флажка 

                          <div class="form-group">
                    <h5>Categories</h5>
                    <label v-for="category in categories">
                    <input v-model="selectedCategories" type="checkbox" :value="category" v-on:click="selectedCategory=category; selectCategory">
                    {{category}}
                    </label>

                </div>

, наконец, у меня есть вычисляемое свойство selectCategory, оно выглядит так 

                  selectCategory: function(){
                      if(this.selectedCategories.length!=0){
                          var templateArray=this.templateArray;
                          for (var i=0; i<this.selectedCategories.length; i++){
                              console.log(i);
          return this.filteredTemplateArray=templateArray.filter((template)=>{
            return template.categoryArray.includes(this.selectedCategories[i]);


              })
}
  }
  }

Я также отображаю информацию шаблона с этим для цикла for 

    <div v-cloak v-bind:key="template.itemId + '_' + index" v-for="(template, index) in selectCategory" class="col-md-4">
            <div class="card">
                <video muted :src="'mysource/'+template.itemId+'/'+template.thumbName+'.mp4'" controls preload="none" controlsList="nodownload nofullscreen" :poster="'mysource/'+template.itemId+'/'+template.thumbName+'.jpg'" loop="loop"></video>
                <div class="card-body">

                    <p class="card-title">{{template.itemName}}</p>
                    <!--end card-title-->
                    <p v-show="displayCount==0" class="card-text">Please create a display to customize</p>
                    <!--end user has no display card-text-->
                    <p v-show="displayCount>0" class="card-text">Custom Text, Custom Colors, Upload Logo</p>
                    <!--end user has display card text-->
                    <p class="card-text">{{template.renderTime}} minutes</p>
                    <a href="#" v-show="loggedIn==true && displayCount>0" class="btn btn-primary btn-block">Customize</a>
                    <!--logged in and has display button-->
                    <a href="#" v-show="loggedIn==false" class="btn btn-primary btn-block" disabled>Customize</a>
                    <!--not logged in button-->
                    <a href="profile.php?showAddDisplayForm=1" v-show="loggedIn==true && displayCount==0" class="btn btn-primary btn-block">Create A Display</a>
                </div>
                <!--end card-body-->
            </div>
            <!--end card-->
        </div>

каждый раз, когда пользователь нажимает на флажок категории, эта функция запускается.Я пытаюсь отфильтровать массив шаблонов и найти элементы, которые содержат выбранные категории.Однако я всегда останавливаюсь на 0, несмотря ни на что.Когда я добавляю более одного элемента, он не работает.Мне нужно убрать все элементы, которые содержат выбранные категории, и если selectedCategories пусто, установить значение FilterTemplateArray в templateArray, чтобы все элементы отображались.Есть идеи как это сделать?

переместите цикл for ниже в методе, как показано.Я также создал наблюдатель, который отслеживает selectedCategories и при его изменении запускает метод, который отфильтровывает дубликаты и устанавливает отфильтрованные категории обратно в исходный массив, когда selectedCategories.length == 0.Это создает фильтр категории, который считает.например, если отмечены спортивные и праздничные дни, будут показаны только все элементы в спорте и все элементы в праздничные дни, которые, кажется, работают лучше, чем обратный отсчет или те, которые существуют только в обоих.Я использую приложение вместо этого в качестве переменной, которую я назвал своим экземпляром vue, и потому что, когда вы углубляетесь в функцию, это не всегда означает приложение. 

  watch: {
      selectedCategories(){
          this.categoryFilter();
      },
          sortBy(){
              this.sortTemplatesBy();
          }
    },
  methods: {
            sortTemplatesBy: function(){ 
      if(this.sortBy == "az") {
        this.filteredTemplateArray.sort(function(a,b) {
          if(a.itemName > b.itemName) {
            return 1;
          }
          if(a.itemName < b.itemName) {
            return -1;
          }
          return 0;
        });
      }

      if(this.sortBy == "dateAdded") {
        this.filteredTemplateArray.sort(function(a,b) {
          if(a.dateAdded < b.dateAdded) {
            return 1;
          }
          if(a.dateAdded > b.dateAdded) {
            return -1;
          }
          return 0;
        });
      }

      if(this.sortBy == "renderTime") {
        this.filteredTemplateArray.sort(function(a,b) {
          return parseInt(a.renderTime) - parseInt(b.renderTime);
        });
      }
    },
      categoryFilter: function(){
          if(app.selectedCategories.length!=0){
          app.filteredTemplateArray=[];
          var templateArray = app.templateArray;
          for(i=0; i<app.selectedCategories.length; i++){
              var filtered=templateArray.filter(function(template){
                  var currentCategory=app.selectedCategories[i];

                  return returnValue;
              });
              console.log(filtered);
              app.filteredTemplateArray=app.filteredTemplateArray.concat(filtered);

      }
          var uniqueArray=[];
          var allResultsArray=app.filteredTemplateArray;
          for(j=0; j<allResultsArray.length; j++){
              if(uniqueArray.indexOf(allResultsArray[j]) == -1){
                  uniqueArray.push(allResultsArray[j])
